Team usa takes on Portugal in the world cup but will have to do it without jozy altidore who sustained that painful hamstring injury and joins us from Brazil. How are you feeling. I'm all right. A little sore. Better than I was Monday. Good to hear. Boy, we could all see it when you pulled up. You must have ghoen right away something was wrong. Yeah, one of those where I knew I couldn't continue as soon as I felt the muscle so it was a little bit unlucky but we have guys that are going to step in and do a great job for us on Sunday. The team certainly came together against Ghana. What's the mood like now? The mood is exciting. Everybody is, you know, really excited. Amped up and ready to go. It's a good opportunity for us, obviously, to get to the next round with a good result against Portugal, so the guys are excited and, you know, up to the challenge. So what's it going to take to beat Portugal? I think a little bit of everything. Just like the gain father game. I think there will be times where we'll have to be on the front foot and other times where we'll have to be defensively very sound and other times where pure will will have to get us through the game so I think we've been prepared for that over the years and I think Portugal will be another good opportunity for us to kind of show that to the world. And they're likely not to have Ronaldo. Yeah, that might help a bit because he a good player. He's world renowned for what he does and somebody that can change a game on a drop of a dime so whether he plays or not, you know, won't really take away from the challenge but obviously him not playing might help a little bit. What's it going to take to get you back on the field. Do you think you'll be able to play against Germany next Thursday? I'm not setting any timetable, just focusing on getting myself right and being the best cheerleader for the team because weaver a lot of good players that will step in and do a great job for us and for myself just staying mentally prepared and just doing my best 0 get back on the field as soon as possible. I hope the team feels all the cheers coming at you from here in the U.S. It's been great. The support we get always from back at home is overwhelming. I mean, you look at grant park in Chicago, amazing the 10,000 people that were there watching the game. It was fantastic so we look forward to the same type of support throughout the tournament. Good luck Sunday, jozy. All right, thank you. Oh, and speaking of support we are all -- well, some of rust sporting -- Some of us. Wow. There we go. Robin sent something in. Guess what she's doing right now? She's wearing her custom Jersey to cheer on the team. There she goes. All our Twitter handles are on the back. All in support of team usa.
